Sagot :

Answer is 20 hours.

Given:

Jenny can make 8 lawns in 5 hours.

The objective is to calculate the time required for her to mow 12 lawns.

Consider the required time as t.

The rate of equation can be represented as,

[tex]\begin{gathered} r=\frac{12}{8} \\ r=4 \end{gathered}[/tex]

Now, the time required can be calculated as,

[tex]\begin{gathered} r=\frac{t}{5} \\ 4=\frac{t}{5} \\ t=20\text{ hours} \end{gathered}[/tex]

Hence, the time required for her to mow 12 lawns is 20 hours.
